UNITED STATES PATENT OFFICEQ CHARLES C. BARTON, OF EDINBURGH, SCOTLAND.

MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 388,390, dated August 28, 1888.

Application filed October 19, 1887. Serial No. 252,852. (No model.) Patented in France December 13, 1887, No. 187.572, and in Belgium December 14, 1887, No. 79,914,

To all whom it may concern:

Be it known that I, CHARLES CASIMIR BAR- TON, a citizen of the United States, residing at the Windsor Hotel, Edinburgh, Scotland, have invented a new and useful Improvement in Mechanical Movements, (for which I have received Letters Patent in France, N 0. 187,572, dated December 13, 1887, and in Belgium, No. 79,914, dated December 14, 1887,) of which the following is a specification. This invention relates to that class of mechanical movements in which reciprocating is converted into intermittent rotary motion, and may be used in connection with a counting or registering device, or with any of the other well-known devices, parts of which have an intermittent rotary motion.

The invention consists of an improved construction and arrangement of parts, which not only allow for such conversion, but also have the additional advantages of allowing for intermittent and irregular length of reciprocating movement and locking of the rotary parts, except during such time as they are being directly operated upon.

The nature of my invention may be briefly described by stating that the driving-shaft of the rotary part of the movement is actuated by an angular plate or toothed wheel which is intermittently rotated by the reciprocating parts which operate upon opposite sides of it, and are so arranged that the plate or wheel is alternately held upon one side until the reciprocating part is about to operate upon the other side. One or more of the angular plates or toothed wheelsmay be employed, and when two or more are used either or all may be caused to actuate rotary shafts and connected gear.

In order that my invention may be clearly understood, reference is made to the accompanying drawings, in which Figure 1 represents a side elevation, partly in section, of the reciprocating mechanism and the arrangement of parts for converting the movement thereof into intermittent rotary motion. Fig. 2 represents a front view, partly in section, of the reciprocating and intermittent rotating part. Fig. 3 is a like view with the .parts in a different or alternate position. Fig.

4 is a plan view of the angular wheel and its shaft, the frame and reciprocating bar being in section. Fig. 5 represents a front elevation of the arrangement when a single reciprocating arm is used to act alternately upon two rotary plates or pieces and alternately to hold same. Fig. 6 is a like view with the parts in a different or alternate position.

The reciprocating parts A may be in the form of a single bent and slotted sheath surrounding the frame B, or two separate rods or reciprocating arms may be used, or a single arm may be employed to operate two or more of the rotating parts.

In Figs. 1, 2, 3, and 4 are shown a single rotating part, 0, mounted upon shaft 1), one end of which is carried in bearings in frame B. Part G is here shown as consisting of a three-toothed wheel, the teeth of which, when at right angles to the plane of motion of the reciprocating part A, being of sufficient length to extend out into said plane of motion.

Referring to Fig. 2, let it be assumed that the reciprocating part A is traveling in the direction of the arrow, when there will be no motion of wheel 0 until the shoulder a comes in contact with tooth d, which it will carry' with it, giving a partial rotation to wheel 0, as the bearing-face a, which is in advance of the shoulder a, will have traveled far enough to permit d to move, and the wheel will then be in the position shown in Fig. 3, where it will be temporarily locked against movement by reason of teeth 01 d being in contact with the flat bearing-face a of the sheath A. On the reverse motion of the sheath A, as indicated by the arrow in Fig. 3, teeth d d are free of the bearing-face a before or just as the shoulder a strikes tooth d.

In Fig. 5 the pieces 0 are about to be operated by slotted rod A, which is supposed to be moving in the direction of the arrow, part a, being justabout to strike and move point d, while point a has just released the face d (1, so that as d is moved and locked by a be tween (1 (1 its motion may be transmitted through gear D and point d brought into the position shown in Fig. 6, ready to be acted upon when part a is brought against it on the return-stroke of rod A. In this construction gear D may beused to impart the intermittent rotary motion to the desired mechanism, either alone or in conjunction with shafts b I), as may be desired.

What I claim is 1. In a device for converting reciprocating into intermittent rotary motion, a reciprocating bar provided with a shoulder and a bean ing-face, in combination with an angular wheel arranged to be turned by the contact of said shoulder and to be locked by the said face, substantially as described.

2. In a device for converting reciprocating into intermittent rotary motion, an angular wheel, in combination with a reciprocating bar provided with a shoulder and with' a bearing-face on opposite sides of said wheel, the shoulders being arranged to alternately contact with and turn the wheel, and the bearingfaces to alternately lock the wheel against rotation after each movement by one of the shoulders, substantially as described.

3. In a device for converting reciprocating into intermittent rotary motion, an angular wheel, in combination with a reciprocating bar provided with bearing-faces a a having shoulders a a, arranged 'on opposite sides of the wheeland one in advance of the other, sub- 7 stantially as described.

at. In a device for converting reciprocating into intermittent rotary motion, the combination of the frame-piece B, the angular wheel 0, having its shaft journaled in piece B, and

the reciprocating sheath partially snrround- 7 W'itnesses:
